Fabian says that 25% of a number will always be greater than 10% of any other number. Complete one inequality to support Fabian's claim and one to show that he is incorrect.

Refute 25% of <10%

Respuesta :

hello

Roger is only correct if you are talking about the same number. 10%of 100 is 10 while 25% of 100 is 25. Ok, roger, you win this round.However, if you are talking about different numbers, it will vary. 25% of 4 is 1 while 10% of 1000 is 100. In this case, the 10% of 1000 is bigger than the 25% of 4. 
Have a nice day

Answer with explanation:

Let one  number be "a" and the other be "b" We have to support the inequality:

  •          Support 25% of a>10% of b

           Let a=100 and b=10

                 Then 25% of 100=25

               and 10% of 10=0.10

            As we know that:

                     25 > 0.10

          Hence, a=100 and b=10 supports Fabian statement.

  • Now we have to refute his claim that is we have to take the example such that his claim is incorrect.

        i.e. we have to show  25% of a < 10% of b

         Let a=1 and b=20

           Then    25% of 1=0.25

               and    10% of 20=2

                     As we know that

                      0.25 < 2

           Hence, for a=1 and b=20 his claim is incorrect.
